Title: Pcm tdm telecommunications exchange systems
IPC: H04Q11/04
Filed: 1972-10-02
Abstract: 1400490 Automatic exchange systems SIEMENS AG 2 Oct 1972 [30 Sept 1971] 45304/72 Heading H4K A telecommunication system includes a plurality of incoming and a plurality of outgoing asynchronous serial PCM, TDM highways corresponding pluralities of serial to parallel and parallel to serial converters, a plurality of storage locations each capable of being addressably associated with an incoming time channel and with an outgoing time channel and of receiving, intermediately storing and transmitting a parallel PCM code. The Figure shows the incoming portion of one such system which is symmetrical about a centre line through stores S1 to S3. The system is sectionalized and under normal conditions channels on the incoming highways PCM ek1 to PCM ek16 of each section 1, 2, 3 normally connected to selected outgoing highway channels via serial to parallel converters PSV, an associated addressable store S1, S2, S3 and parallel to series converters associated with the outgoing highways. The converters are coupled to and from the associated store via intermediate super highways such as Ze1 and a switch arrangement such as K1. The superhighways normally only provide service for one section but each extend to an adjacent section so as to be able to cover two sections with reduced service during fault conditions. To provide two directions of transmission two separate incoming and two separate outgoing channels are used for each connection. The addressable stores Sl to S3 and the addressed switch arrangements such as K1 are controlled by separate cyclic stores and associated decoders. Phase compensations to be effected due to asynchronous working are permanently stored at a central point and used in a manner not detailed to adjust the timing of the address signals.
Patent GB-940096-A (GB)
Title: Method of recording electrical signals
IPC: H04N5/76
Filed: 1961-12-18
Abstract: 940,096. Television. GRETAG A.G. Dec. 18, 1961 [Dec. 27, 1960], No. 45331/61. Heading H4F. [Also in Divisions G1 and G4] In a method of recording electrical signals, a thin film of a substance, the degree of polymerization of which is variable by electron irradiation, is subjected to the action of an electron beam modulated by the signal to be recorded, and the resultant local differences in the degree of polymerization are converted into local differences in film thickness. The invention is stated to be of application generally in the recording of electrical signals but is described only in relation to the recording of image signals where the film is subjected to a point-bypoint control by an electron beam so as to produce a recording in the form of an image corresponding to the original image represented by the signals. The substances used to make the film may be selected from those in which either polymerization or depolymerization occurs on electron irradiation. The local differences in thickness are brought about either by swelling the film by weak solvents or plasticizers or by dissolving away the film, the swelling or dissolution being greatest in the regions which are least polymerized. Suitable materials are high-polymer substances having large molecules which are not cross-linked, the higher the molecular weight, the greater the recording sensitivity. Examples are quoted based on gelatin which is either dissolved away by hot water or swollen with a water-glycerin solution, rubber which is either dissolved away with petroleum ether or swollen with a petroleum ether mineral oil solution, and methyl methacrylate which is dissolved away by a mixture of petroleum ether and chloroform. Reference is also made to the use of silicone rubber. The recorded image may be reproduced by direct optical projection in a Schlieren optical system. Alternatively, a variable density record may be produced by dyeing the recording either before or after the production of the thickness variation. Reference is also made to the use of a dye-containing layer combined with the recording layer. Reference is made to the use of the invention for producing printing plates.

Title: Reciprocating Hydraulic Pumps
IPC: F04B1/12
Filed: 1966-10-11
Abstract: 1,169,947. Reciprocating pumps. INTERNATIONAL BASIC ECONOMY CORP. Oct. 11, 1966 [Oct.12, 1965], No.45447/66. Heading F1A. [Also in Division G3] In an hydraulic pump having a cylinder block 70 mounted in a housing 20 and at least one cylinder 78 in the block, the cylinder is provided with two axially spaced outlets 81 and 102 through which the piston 62 delivers in succession during a pumping stroke. Pressure responsive valves 87 and 96 are associated with the respective cylinder outlets 81 and 102. The flow from the plurality of outlets 81 passes around the block 70 to valved outlet 222 and may provide cooling for the pump. The flow from outlets 102 passes to an outlet 116 via block passages 122, passages 112 in members 110, spring and pressure biased against the block 70, and housing passages 114. Liquid flows into the cylinders 78 through housing inlet 80 and valve controlled passages 88 in the pistons 62 or inlet ports in the cylinder block. To vary the ratio of liquid delivered through the outlets 116 and 222 the block 70 is movable against the bias of the spring 142 by a piston 146. Liquid under pressure is delivered to a chamber 150, defined between the piston 146 and the housing 22, under the control of a unit 135. The adjustable spring-biased spool 149 in the unit 135 is subject to the pressure at the cylinder outlets 102 through passages 122-A, 140, 144, 147 and serves to connect the chamber 150 to the outlets 102 via passages 130 and 162 or to the chamber 93 around the block 70 through passages 160 and 178. The block 70 is guided by bearing members (76, Fig. 8, not shown), mounted in recesses (72 and 74) in the block and housing. The piston shoes 56 are of nylon. To provide pump cooling the flow from the outlet (222, Fig. 7, not shown), leads to a heat exchanger (260) and is then forced through a fine filter (262) to a reservoir (250). Liquid is drawn from the reservoir (250) through a wire screen filter (252) to the pump inlet (80).

Abstract: 1,070,470. Winding webs. HONEYWELL Inc. Nov. 25, 1963 [Nov. 27, 1962], No. 46481/63. Heading B6B. [Also in Division G1] Take-up mechanism for the record paper or film 9 of an oscillographic recorder comprises an idler roller 8 sensing the tension in a web of paper 9 being taken up by a spool 12 and linkage 6, 624, 13 amplifying the movement of the roller 8 mounted on link 6 to cause a control pulley 4 mounted on link 13 to vary its pressure on the slack side of a belt 11 and thus to maintain the tension in the paper 9 constant by controlling the driving torque applied through the belt 11, by a driving drum 2 to a pulley 10 mounted on spool 12. The roller 8 and pulley 4 are urged against the paper 9 and belt 11, respectively, by a spring 7, whose tension can be adjusted to vary this bias. The belt 11 may be composed of woven glass fibres impregnated with nylon or it may be woven nylon. The belt is trained over the smooth outer surface of drum 2, conveniently made of stainless steel and co-operates therewith to form a slipping clutch. The amount of the belt 11 in contact with the drum 2 may be increased by the use of an idler roller 15 and the angle the paper 9 takes as it leaves roller 8 can be held constant by the use of another idler roller 14.

Abstract: 1440683 Clutch control BORG-WARNER CORP 5 Oct 1973 [20 Nov 1972] 46648/73 Heading F2L A temperature controlled multi-plate slipping clutch 80 for driving a fan 12 of an internal combustion engine is spring 96 engaged and disengaged by pneumatic pressure supplied through a temperature controlled valve 20. The clutch 80 interconnects an input member 61 driven by pulleys engaging in grooves 66 and an output member 51 to which is fixed the fan 12, both input and output members being mounted for rotation on a fixed shaft 32. The clutch engaging springs 96 act between a fixed reaction member 92 and a clutch actuating member 91 which in turn acts on a clutch presser member 82 through a thrust bearing 97. The pneumatic pressure is supplied to a chamber 109 on the opposite side of reaction member 92 from the springs 96. The valve 20 has a sensor 139 positioned in the engine cooling system and decreases the pneumatic pressure in chamber 109 as the temperature rises to decrease clutch slip, and vice versa for a temperature drop. The inside of input member 61 contains lubricant for the clutch 80 and bearings and this is withdrawn by a scoop 117 (Fig. 4, not shown) passed through passages 41, 42 to a heat exchanger 22 and returned via passages 45, 46, 47 to the clutch. The temperature responsive valve 20 is shown in detail in Fig. 3 and comprises a sensor portion 139 within the engine cooling system which has a movable portion 141 which abuts a plunger 169, biased against portion 141 by a spring 174 and having a central bore 179 to which inlet fluid to the valve from a port 132 enters through apertures 177. The end of bore 179 remote from sensor 139 abuts a valve seal 181 of a spring-biased piston 184 in one part of a chamber 156 divided in two by a piston 154, biased to the right by a spring 162 and having a valve seat 166 in abutment with the piston 184. The outlet from the valve 20 is by a port 133, and a vent port 168 is also provided. On increase of temperature the portion 141 moves to the right, which moves plunger 169 to the right, which moves piston 184 to open valve seat 166 and vent fluid from the right hand side of piston 154 through aperture 167 and vent port 168 (and so from chamber 109 in the clutch) the spring 162 moving the piston to the right due to the pressure drop and so reclosing the valve seat 166. On drop of temperature the plunger 169 moves to the left to open valve seat 181 and allow fluid from the inlet 132 to pressurize the right hand side of piston 154 (and chamber 109) which increase moves piston 154 to the left, which movement is followed by piston 184 to close valve seat 181. The outlet pressure is thus set according to temperature, and may be varied using different spacers 175 between sensor and plunger.
